Bachelor of Engineering Interview Questions and Answers

Lapping lengths of steel refer to the overlapping distance required in steel reinforcement to ensure proper bonding.

• Lapping lengths are necessary to provide continuity and strength in reinforced concrete structures.

• The lapping length depends on the diameter of the steel bars and the design requirements.

• It is important to follow the lapping length specifications provided by structural engineers or building codes.

• For example, in a typical lap splice, the lapping length for 12mm...read more

Steel rusts in concrete due to the presence of moisture and oxygen.

• Steel is primarily made of iron, which is prone to rusting.

• Concrete is a porous material that can absorb and retain moisture.

• Moisture in concrete creates an electrolytic environment that promotes rusting.

• Oxygen from the air reacts with iron in the steel to form iron oxide (rust).

• Rust formation can lead to the expansion of steel, causing cracks and weakening the structure.

The quantity of steel can be calculated by determining the required steel reinforcement as per the design specifications.

• Calculate the required steel reinforcement based on the design drawings and specifications

• Consider factors such as structural load, concrete strength, and design codes

• Use formulas or software tools to determine the quantity of steel required

• Account for wastage and additional reinforcement for critical areas

• Consult structural engineers or reference manuals f...read more
